Sorry I've been out of the country. I used a combination. What I suggest however is sew a sample block together because I did have problems with matching seems and points. I used the 60% for the large triangles and I marked another ruler with the smaller template size. It actually didn't go together very easily.Whichever way you go sew a sample first then you will know how to cut to the right size. If I recall when I sewed two small triangles together they were a bit larger than the large triangles. Hope this makes sense. good luck. It could also be that all the problems have been solved. I was one of the early ones, when it was still a mystery quilt.
